The army base where Prince Harry is based was the scene of a firefight which has left two U.S. members of the U.N. force in Southern Afghanistan dead.

There is as yet no word whether or not Harry was caught up in the melee, however the British Army will now face renewed questions about whether posting Harry to Afghanistan endangers other soldiers.

The Taliban vowed to do everything in its power to kill or capture Prince Harry, 27, who is third in line to the British throne, after British forces announced his deployment last week.

U.S. and U.N. officials told NBC that the attack, involving small arms and mortars, was launched against the International Security Assistance Force shortly after midnight local time (3 p.m. ET). Camp Leatherneck, the U.S. Marine half of the base, took the brunt of the attack, officials said.
